Cost of admission?

I went last week. I asked the person at cashier to charge me 1 adult $10 and 1 student $6, but was charged $20. Some parts were closed and it needs so TLC.

In the Summer I paid 6 dollars per person.

I paid $8.00, I am retired military.

10$ warning it is over priced

We used Groupon for admission and it was a few dollars cheaper, and included a free soda.

$10 for adults, $8 for seniors and Military with ID and $6 for children.

Adults - 10 Dollars Children - 6 Dollars
